Y Application filed bcezii'ber 18, 1924-, Serial No. 756,851, and smash myrat In such internal combustion motors where the fuel is injected without being previously gasified, it is often necessary to in ect a quantity of fuel by hand before starting can take place, and after the motor has been started the governor controlling the length of stroke of the pump during operation must also be controlled by hand according to the prevailing load on the motor. I

To perform this, access was hitherto only had to comparatively inadequate means, inadequate chiefly for the reason that they were mounted in different places of the motor, so that it was necessary to operate them each per se.

'The present invention has for. its purpose to unite the said devices into a single device,

by means of which the above-mentioned operations may be performed'. 7 I

The invention is principally characterized by a member (or mechanism) adapted to be operated by hand, said member ormechanism being on the one hand so connected with the fuel pump that the latter may be caused to pump by means of the said member or mechanism which, on the other hand, is associated with the governor of the fuel pump in such a manner that this governor may also be adj usted by means of the said member (or mechanism) in accordance with the prevailing load on the motor. f

The arrangement may preferably be'such that the member operated by hand is adapted I to be rotated and screwed so that the same will in a certain angular position, and while Cil plunger or the member influencing the latter, so as to effect the pumping by hand, whereas, in another angular pos1t1on,the said member will respectively strain or unload a'spring connected therewith, said spring counteract ing the deflection: of the pump governor driven by the motor.

The'accompanying drawing illustrates a device arranged in the manner last set forth. Fig, 1 shows the same in vertical section and Fig. 2 is an external View of the device takenv I wherein the manually operable adjusting at right angles to Fig. 1. I l

1 is the plunger of the fuel pump, the suction stroke of which is broughtabo'ult by the spring 2 while the pressure stroke is effected by the member 3 which is rotatably mounted about the pin 4:, and provided with the sliding roller 5 bearing on the cam 6. Thelatter'is se. dieplaceahly but not rotatably mounted. on the America is it is being turned to and fro, actuate the pump 7 I pump plunger on Sflld'SllPPOlt, a stroke regulating member for the plunger, a spring conspindle 14; driven by the motor, and is movably connected to the governor weights 7 sup ported by the spindle 14 and adapted to make deflections, and thereby to displace the cam 6 against the action of the spring 8. The

7 spring 8 is compressed between the cross head 9 of the governor and a casing 10 which latter forms the most prominent detail of the arrangement. The casing 10 is adapted to be v .65

rotated and screwed about the fixed body 11 surrounding the spindle 14, and is provided on the outside with a handle 12 by means of which the casing may be rotated. .The edge of the casing has an abutment 13 which is,

prior to the motor being started, situated adjacent the part 3. 1 l

The handle 12 being grasped so as to turn v the casing 10 to the left according to the drawis performed by turning the casing to and fro a sufficient number of times.

. After the motor has been started, the casing Z is again turned in the one or the other direction so that the governor spring 8 is compressed or expanded, according as a larger or smaller quantity of fuel is to be injected.

What I claim as new and desire to secure by Letters Patent of the United States of 1. An arrangement in internal combustion motors for pumping fuel to effect starting and adjustmentof the pump governor, including in combination, a support, a springlnounted trolled governor coacting with the regulating member and manually operable means arranged about the governor and adj ustably engaged with the support so that when adjusted thereon it will actuate the regulating member and thereb the plunger and will in addition effect an a justment of the spring controlled governor.

2. An arrangement as claimed in claim 1 extending from the lower edge of the menr her for coacting with the stroke regulating member.

An arrangement as claimed in claim 1- 'manually operable means, substantially as and for the purposes set forth.

4. An arrangementas claimed in claim 1 10 wherein the stroke regulating member in cludes a full crank lever pivotally mounted on the-support having one arm disposed between the plunger and the manually operable adjusting means and the other arm engaging a l the governor.

In testimony whereofI affix my signature.
